Description

この発明は、ノート型パーソナルコンピュータなどの携帯型電子機器、およびその表示パネルを内蔵した表示装置に関する。   The present invention relates to a portable electronic device such as a notebook personal computer and a display device incorporating the display panel.

従来、携帯型電子機器として、例えば、表示パネルの筐体をＰＣ本体に対して開閉可能に取り付けたノート型パーソナルコンピュータ（以下、ノートＰＣと称する）が知られている。このノートＰＣは、携帯することを前提に設計されており、特に表示パネルの筐体には高い剛性が必要とされている。   2. Description of the Related Art Conventionally, as a portable electronic device, for example, a notebook personal computer (hereinafter referred to as a notebook PC) in which a display panel casing is attached to a PC main body so as to be opened and closed is known. This notebook PC is designed on the assumption that it is carried, and high rigidity is particularly required for the casing of the display panel.

このため、筐体の補強構造として、筐体の背面側に矩形板状の透明アクリル板を補強部材として貼り付けた構造が知られている（例えば、特許文献１参照。）。この補強部材は、筐体背面全体を略覆う大きさに形成され、その縁部が筐体背面に接着されている。   For this reason, the structure which affixed the rectangular-plate-shaped transparent acrylic board as a reinforcement member on the back side of a housing | casing is known as a reinforcement structure of a housing | casing (for example, refer patent document 1). The reinforcing member is formed in a size that substantially covers the entire back surface of the housing, and an edge thereof is bonded to the back surface of the housing.

このように、筐体の背面側、すなわち表側全面に補強部材を貼り付けることにより、筐体の厚さを必要以上に厚くすることなく、強度を高めることができる。また、筐体背面に傷がついた場合であっても、補強部材を交換するだけで傷の補修が可能となる。   In this way, by attaching the reinforcing member to the rear side of the casing, that is, the entire front side, the strength can be increased without increasing the thickness of the casing more than necessary. Moreover, even when the back surface of the housing is scratched, the scratch can be repaired by simply replacing the reinforcing member.

しかし、上述したように、補強部材を筐体と略同じ大きさにすると、筐体の周縁部近くの強度を高めることができる反面、筐体中央近くの強度を十分に高くすることができない。中央近くの強度を高くするためリブ等を設ける方法も考えられるが、その分筐体が厚くなってノートＰＣが厚くなってしまう。
特開２００３−１５５３０号公報（段落［００５９］、図５） However, as described above, if the reinforcing member is approximately the same size as the casing, the strength near the peripheral edge of the casing can be increased, but the strength near the center of the casing cannot be sufficiently increased. In order to increase the strength near the center, a method of providing a rib or the like is also conceivable. However, the casing becomes thicker and the notebook PC becomes thicker.
JP 2003-15530 A (paragraph [0059], FIG. 5)

この発明の目的は、表示パネルの筐体を薄くでき十分な強度を付与できる表示装置、および携帯型電子機器を提供することにある。   An object of the present invention is to provide a display device and a portable electronic device that can make the casing of the display panel thin and give sufficient strength.

上記目的を達成するため、本発明の表示装置は、表示パネルと、この表示パネルの背面側を覆う筐体と、この筐体と異なる材料により形成され該筐体の略全長に亘って第１方向に延び且つ上記第１方向と交差する第２方向に関して上記筐体を部分的に覆うように該筐体の外面に貼り付けられた補強板と、を有する。   In order to achieve the above object, a display device of the present invention includes a display panel, a casing that covers the back side of the display panel, and a first material that is formed of a material different from that of the casing and extends over substantially the entire length of the casing. And a reinforcing plate attached to the outer surface of the casing so as to partially cover the casing in a second direction that extends in a direction and intersects the first direction.

上記発明によると、表示装置の筐体の外面に部分的に貼り付けられた補強板が第２方向に関して筐体より短くされているため、少なくとも第２方向に沿った補強板の剛性を高めることができ、補強板の大きさを筐体より十分に小さくした上で補強強度を高めることができる。   According to the above invention, since the reinforcing plate partially attached to the outer surface of the housing of the display device is shorter than the housing in the second direction, at least the rigidity of the reinforcing plate along the second direction is increased. The reinforcing strength can be increased after the size of the reinforcing plate is made sufficiently smaller than the casing.

また、本発明の表示装置は、表示パネルと、この表示パネルの背面側を覆う樹脂製の筐体と、少なくとも軽金属を含む材料により形成され上記筐体の外面を部分的に覆うように該筐体の略全長に亘って貼り付けられた補強板と、外部装置との間で無線通信をするため、上記補強板と重ならない位置に配置されたアンテナと、を有する。   The display device of the present invention includes a display panel, a resin casing that covers the back side of the display panel, and a casing that is formed of a material containing at least light metal and partially covers the outer surface of the casing. In order to perform wireless communication between the reinforcing plate attached over substantially the entire length of the body and the external device, the antenna is disposed at a position not overlapping the reinforcing plate.

上記発明によると、加工が容易で軽量安価な樹脂により筐体を形成し、金属製の補強板を部分的に貼り付けて、補強板に重ならない位置にアンテナを配置したため、金属製の補強板によってアンテナの通信性能が損なわれることがない。   According to the above invention, the metal reinforcement plate is formed because the housing is formed of a resin that is easy to process and is lightweight and inexpensive, the metal reinforcement plate is partially attached, and the antenna is disposed at a position that does not overlap the reinforcement plate. Thus, the communication performance of the antenna is not impaired.

この発明の表示装置、および携帯型電子機器は、上記のような構成および作用を有しているので、表示パネルの筐体を薄くでき十分な強度を付与できる。   Since the display device and the portable electronic device of the present invention have the above-described configuration and operation, the casing of the display panel can be made thin and sufficient strength can be imparted.

以下、図面を参照しながらこの発明の実施の形態について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１には、この発明の実施の形態に係る携帯型電子機器として、ノート型パーソナルコンピュータ１（以下、単に、ノートＰＣ１と称する）の概略斜視図を示してある。また、図２には、このノートＰＣ１の表示装置２をＰＣ本体４（機器本体）に対して開放した状態の概略斜視図を示してある。   FIG. 1 is a schematic perspective view of a notebook personal computer 1 (hereinafter simply referred to as a notebook PC 1) as a portable electronic device according to an embodiment of the present invention. FIG. 2 is a schematic perspective view showing the state in which the display device 2 of the notebook PC 1 is opened with respect to the PC main body 4 (device main body).

図２に示すように、ノートＰＣ１は、ＰＣ本体４のリア側に２つのヒンジ部３を介して表示装置２を開閉可能に取り付けて構成されている。ＰＣ本体４の上面（前面）には、オペレータによる入力装置として機能するキーボード６等が配置されており、図１に示すように表示装置２を閉じることでキーボード６が閉塞される。一方、表示装置２は、閉じたときにキーボード６に対面する画面を有する表示パネル８を内蔵している。   As shown in FIG. 2, the notebook PC 1 is configured by attaching the display device 2 to the rear side of the PC main body 4 via two hinge portions 3 so as to be opened and closed. On the upper surface (front surface) of the PC main body 4, a keyboard 6 or the like that functions as an input device by an operator is disposed, and the keyboard 6 is closed by closing the display device 2 as shown in FIG. On the other hand, the display device 2 has a built-in display panel 8 having a screen that faces the keyboard 6 when closed.

表示装置２は、表示パネル８の背面側を覆うように取り付けられた樹脂製の筐体１０を有する。筐体１０の外面には、アルミニウム板を加工した補強板２０が筐体表面を部分的に覆うように貼り付けられている。本実施の形態では、補強板２０は、略矩形板状に形成され、表示装置２の短手方向（第２方向）に沿ってヒンジ部３に近い側に偏った位置に貼り付けられており、表示装置２の長手方向（第１方向）略全長に亘って延びた縁部２１を有する。本実施の形態では、補強板２０が筐体１０の長手方向全長に亘って設けられ且つ筐体１０の短手方向略半分を覆う大きさに形成されているため、長手方向に沿った縁部２１が筐体１０の略中央を通っている。   The display device 2 includes a resin casing 10 attached so as to cover the back side of the display panel 8. A reinforcing plate 20 made of an aluminum plate is attached to the outer surface of the housing 10 so as to partially cover the surface of the housing. In the present embodiment, the reinforcing plate 20 is formed in a substantially rectangular plate shape, and is affixed to a position that is biased toward the side closer to the hinge portion 3 along the short direction (second direction) of the display device 2. The display device 2 has an edge portion 21 extending substantially over the entire length in the longitudinal direction (first direction). In the present embodiment, the reinforcing plate 20 is provided over the entire length in the longitudinal direction of the housing 10 and is formed to have a size that covers substantially half of the housing 10 in the short direction, so that the edge along the longitudinal direction. 21 passes through the approximate center of the housing 10.

このように、表示装置２の短手方向に関して筐体１０の外面を部分的に覆うサイズの補強板２０を貼り付けることにより、補強板２０の短手方向に沿った剛性を高めることができ、その結果、筐体１０の剛性を高めることができる。つまり、従来のように補強板を筐体と略同じ大きさにして筐体の全面に貼り付けると、筐体の中央部において十分な剛性を得ることができないが、本実施の形態のように補強板の１方向に沿った長さを短くすることで、少なくとも短くした方向に関する剛性を高めることができる。また、補強板２０の縁部２１が筐体１０の略中央を通って配置されているため、この縁部２１を筐体１０に接着することで、中央部の剛性をも高めることができる。   Thus, by sticking the reinforcing plate 20 of a size that partially covers the outer surface of the housing 10 in the short direction of the display device 2, the rigidity along the short direction of the reinforcing plate 20 can be increased. As a result, the rigidity of the housing 10 can be increased. In other words, if the reinforcing plate is attached to the entire surface of the casing with the same size as the casing as in the prior art, sufficient rigidity cannot be obtained at the center of the casing. By shortening the length of the reinforcing plate along one direction, the rigidity in at least the shortened direction can be increased. Further, since the edge portion 21 of the reinforcing plate 20 is disposed through substantially the center of the housing 10, the rigidity of the center portion can be increased by bonding the edge portion 21 to the housing 10.

以下、図３乃至図８を参照して、上述した表示装置２の構造についてさらに詳細に説明する。図３には、ノートＰＣ１を短手方向に沿って切断した断面図を示してあり、図４には、補強板２０を筐体１０の凹部１１から取り外した状態をノートＰＣ１のリア側から見た斜視図を示してあり、図５には、筐体１０の凹部１１から取り外した補強板２０の斜視図を示してあり、図６には、補強板２０を裏側から見た斜視図を示してあり、図７には、筐体１０の凹部１１と補強板２０との間の接続部分を拡大した断面図を示してあり、図８には、表示パネル８を取り外した状態の筐体１０の内面側の斜視図を示してある。   Hereinafter, the structure of the above-described display device 2 will be described in more detail with reference to FIGS. 3 to 8. FIG. 3 shows a cross-sectional view of the notebook PC 1 cut along the short direction, and FIG. 4 shows a state in which the reinforcing plate 20 is removed from the recess 11 of the housing 10 as viewed from the rear side of the notebook PC 1. 5 is a perspective view of the reinforcing plate 20 removed from the recess 11 of the housing 10, and FIG. 6 is a perspective view of the reinforcing plate 20 viewed from the back side. FIG. 7 shows an enlarged cross-sectional view of a connection portion between the recess 11 of the housing 10 and the reinforcing plate 20, and FIG. 8 shows the housing 10 with the display panel 8 removed. The perspective view of the inner surface side of is shown.

表示装置２は、上述したように、表示パネル８、筐体１０、補強板２０などを組み合わせて構成されている。具体的には、表示装置２は、図８に示す筐体１０の内側に表示パネル８を収容配置し、表示パネル８の前面周縁部に図２に示すような矩形枠状のフレーム１２を取り付け、筐体１０の背面に形成された凹部１１に図５に示す補強板２０を貼り付けて組み立てられる。   As described above, the display device 2 is configured by combining the display panel 8, the housing 10, the reinforcing plate 20, and the like. Specifically, the display device 2 accommodates and arranges the display panel 8 inside the housing 10 shown in FIG. 8, and a rectangular frame 12 as shown in FIG. 2 is attached to the front peripheral edge of the display panel 8. The reinforcing plate 20 shown in FIG. 5 is attached to the recess 11 formed on the back surface of the housing 10 for assembly.

本実施の形態では、表示パネル８は、液晶ディスプレイ（ＬＣＤ）であり、バックライトとして機能する図示しない蛍光ランプを内蔵している。また、図４に示すように、表示パネル８の裏面側には、図示しない駆動回路を接続するための配線基板９が接続されている。配線基板９は、ヒンジ部３近くで表示装置２の長手方向に延設され、表示パネル側の図示しない接続端子に圧着されている。   In the present embodiment, the display panel 8 is a liquid crystal display (LCD) and incorporates a fluorescent lamp (not shown) that functions as a backlight. Further, as shown in FIG. 4, a wiring board 9 for connecting a drive circuit (not shown) is connected to the back side of the display panel 8. The wiring board 9 extends in the longitudinal direction of the display device 2 near the hinge portion 3 and is crimped to a connection terminal (not shown) on the display panel side.

筐体１０は、表示パネル８の背面側を覆うように配置されている。筐体１０の外面には、補強板２０を収容配置するための凹部１１が形成されている。また、この補強板２０が重なる凹部１１には、図４に示すように、３つの開口部１３が形成されている。各開口部１３の縁には、その全周に亘って補強板２０に向けて突出した環状の壁部１４が形成されている。この環状の壁部１４は、開口部１３の周囲の凹部１１に接着剤を塗布して補強板２０を接着固定する際に、接着剤が開口部１３内に流入してしまうことを防止するよう機能する。   The housing 10 is disposed so as to cover the back side of the display panel 8. A recess 11 for accommodating and arranging the reinforcing plate 20 is formed on the outer surface of the housing 10. Further, as shown in FIG. 4, three openings 13 are formed in the recess 11 where the reinforcing plate 20 overlaps. An annular wall portion 14 is formed on the edge of each opening 13 so as to protrude toward the reinforcing plate 20 over the entire circumference. The annular wall 14 prevents the adhesive from flowing into the opening 13 when the adhesive is applied to the recess 11 around the opening 13 and the reinforcing plate 20 is bonded and fixed. Function.

さらに、図８に示すように、筐体１０が表示パネル８に対向する内面には、図示しない外部装置との間で無線通信するための２つのアンテナ１５が貼り付けられており、開口部１３およびアンテナ１５の機能部１５ａを除く略全面にシールド部材１６が設けられている。本実施の形態では、シールド部材１６は、アルミニウムを筐体１０の内面に蒸着することで形成される。   Further, as shown in FIG. 8, two antennas 15 for wireless communication with an external device (not shown) are attached to the inner surface of the housing 10 facing the display panel 8. The shield member 16 is provided on substantially the entire surface excluding the functional portion 15a of the antenna 15. In the present embodiment, shield member 16 is formed by evaporating aluminum on the inner surface of housing 10.

すなわち、アンテナ１５は、金属性の補強板２０と重ならない位置に配置されており、且つアンテナ１５の機能部１５ａにシールド部材１６が重ならないようになっているため、補強板２０またはシールド部材１６によってアンテナ１５による通信性能を低下させることがない。   That is, the antenna 15 is disposed at a position that does not overlap with the metallic reinforcing plate 20, and the shield member 16 does not overlap the functional portion 15 a of the antenna 15. Therefore, the communication performance by the antenna 15 is not deteriorated.

補強板２０は、筐体１０の外面側に形成された凹部１１に取り付けられる。補強板２０は、図５および図６に示すように、その長手方向両端２２が筐体１０の凹部の形状に合わせて同じ方向に折り曲げられており、縁部２１から離間した長辺２３も僅かに折り曲げられてリブ２４を構成している。このように、補強板２０の長手方向に沿ったリブ２４を形成することで、補強板２０の長手方向に沿った剛性をも高められている。   The reinforcing plate 20 is attached to the concave portion 11 formed on the outer surface side of the housing 10. As shown in FIGS. 5 and 6, both ends 22 of the reinforcing plate 20 are bent in the same direction according to the shape of the concave portion of the housing 10, and the long side 23 separated from the edge 21 is slightly The ribs 24 are formed by being bent in the above-described manner. Thus, by forming the rib 24 along the longitudinal direction of the reinforcing plate 20, the rigidity along the longitudinal direction of the reinforcing plate 20 is also enhanced.

また、補強板２０は、図３に示すように筐体１０の凹部１１に取り付けられた状態で、図７に拡大して示すように、その縁部２１が筐体１０の外面１０ａより凹部１１に向けて僅かに退避している。つまり、樹脂製の筐体１０に対して金属製の補強板２０を貼り付けるため、補強板２０の縁部２１が筐体１０の外面１０ａより突出していると、ノートＰＣ１の携帯時にユーザの手を傷つける可能性がある。このため、本実施の形態では、補強板２０の縁部２１が筐体１０の外面１０ａから突出しないように縁部２１を凹部１１に埋設した。   Further, the reinforcing plate 20 is attached to the recess 11 of the housing 10 as shown in FIG. 3, and its edge 21 is recessed from the outer surface 10 a of the housing 10 as shown in FIG. Evacuated slightly toward That is, if the edge 21 of the reinforcing plate 20 protrudes from the outer surface 10a of the casing 10 in order to affix the metal reinforcing plate 20 to the resin casing 10, the user's hand when carrying the notebook PC 1 May hurt. For this reason, in the present embodiment, the edge 21 is embedded in the recess 11 so that the edge 21 of the reinforcing plate 20 does not protrude from the outer surface 10 a of the housing 10.

そして、補強板２０は、筐体１０の凹部１１に取り付けられた後、図４および図８に示す導電性テープ１７により、開口部１３を介してシールド部材１６と電気的に接続される。これにより、シールド部材１６を形成できない開口部１３の領域に配置した補強板２０をシールド部材として機能させることができ、ノートＰＣ１から外部に漏れる電磁波を効果的に遮蔽することができる。   Then, after the reinforcing plate 20 is attached to the concave portion 11 of the housing 10, the reinforcing plate 20 is electrically connected to the shield member 16 through the opening 13 by the conductive tape 17 shown in FIGS. 4 and 8. Thereby, the reinforcement board 20 arrange | positioned in the area | region of the opening part 13 which cannot form the shield member 16 can be functioned as a shield member, and the electromagnetic waves which leak outside from the notebook PC 1 can be shielded effectively.

また、筐体１０の開口部１３を介して補強板２０に対向する表示パネル８の背面には、電子部品１８が突設されている。表示パネル８の背面から突設された電子部品１８があると、筐体１０に外部から応力が作用したとき、電子部品１８の位置で応力が集中して表示パネル８の破壊の原因となる。このため、本実施の形態のように、突出した電子部品１８の位置に筐体１０の開口部１３を形成することで、筐体１０の厚さ分だけ撓みのマージンを稼ぐことができ、応力の集中を防止できる。   An electronic component 18 projects from the back surface of the display panel 8 facing the reinforcing plate 20 through the opening 13 of the housing 10. If there is an electronic component 18 projecting from the back surface of the display panel 8, when stress is applied to the housing 10 from the outside, the stress is concentrated at the position of the electronic component 18, causing the display panel 8 to break. For this reason, as in the present embodiment, by forming the opening 13 of the housing 10 at the position of the protruding electronic component 18, a bending margin can be gained by the thickness of the housing 10. Can be prevented.

以上のように、本実施の形態によると、筐体１０の短手方向に関して約半分の幅の補強板２０を凹部１１に貼り付けたため、補強板２０の短手方向に沿った剛性を高めることができ、補強板を全面に設ける場合と比較して装置を軽量化できる。また、筐体１０の外面１０ａを部分的に覆うように補強板２０を貼り付けたため、補強板２０の無い位置にアンテナ１５を配置でき、通信性能を損なうことがない。   As described above, according to the present embodiment, since the reinforcing plate 20 having a width about half that of the casing 10 in the short direction is attached to the recess 11, the rigidity of the reinforcing plate 20 along the short direction is increased. The weight of the apparatus can be reduced as compared with the case where the reinforcing plate is provided on the entire surface. Further, since the reinforcing plate 20 is attached so as to partially cover the outer surface 10a of the housing 10, the antenna 15 can be disposed at a position where the reinforcing plate 20 is not present, and communication performance is not impaired.

また、本実施の形態によると、表示パネル８に配線基板９を接続した部位、すなわち、外部からの応力によって破損し易い部位を覆う位置に選択的に補強板２０を配置でき、携帯に適したノートＰＣ１を提供できる。   In addition, according to the present embodiment, the reinforcing plate 20 can be selectively disposed at a position covering a portion where the wiring board 9 is connected to the display panel 8, that is, a portion easily damaged by external stress, and is suitable for carrying. A notebook PC 1 can be provided.

また、本実施の形態では、筐体１０の補強板２０が重なる部位、すなわち筐体１０の凹部１１に３つの開口部１３を形成したため、その分、筐体１０を軽量化でき、材料費を削減できる。また、表示パネル８の背面から突設された電子部品１８の位置に筐体１０の開口部１３を形成したため、凹部１１を覆う補強板２０に外部から応力が作用した場合、筐体１０の厚さ分だけ補強板２０の撓みのマージンをとることができ、電子部品１８に補強板２０が接触する可能性を低くできる。   Further, in the present embodiment, since the three openings 13 are formed in the portion where the reinforcing plate 20 of the housing 10 overlaps, that is, the concave portion 11 of the housing 10, the housing 10 can be reduced in weight and the material cost can be reduced. Can be reduced. In addition, since the opening 13 of the housing 10 is formed at the position of the electronic component 18 projecting from the back surface of the display panel 8, the thickness of the housing 10 is increased when external stress is applied to the reinforcing plate 20 that covers the recess 11. The margin of bending of the reinforcing plate 20 can be taken as much, and the possibility that the reinforcing plate 20 contacts the electronic component 18 can be reduced.
